Abstract: The invention comprises a method of isolating at least some of the high molecular weight organic compounds containing basic groups such as proteins, polypeptides, bacteria, virus and enzymes, from solutions containing them, by the steps of bringing the solution into contact with a lignocellulosic material which has been sulphonated to such an extent that its ion exchange capacity reaches to at least 0.15 milliequivalents per gram, and separating the solution from the sulphonated lignocellulosic material.
Abstract translation: 本发明包括通过使溶液与木质纤维素材料接触的步骤，从含有它们的溶液中分离至少一些含有碱性基团如蛋白质，多肽，细菌，病毒和酶的高分子量有机化合物的方法 其已被磺化至其离子交换容量达到每克至少0.15毫当量，并将溶液与磺化的木质纤维素材料分离。

Abstract: Sulphite waste liquor is concentrated in a plural effect evaporator; the so-removed vent steam containing SO2 is cooled at low pressure and the condensate discharged; and the resulting gas rich in SO2 is compressed to atmospheric pressure in a vacuum pump requiring little or no sealing water.
Abstract translation: 亚硫酸盐废液集中在多效蒸发器中; 如此排出的含SO2的排气蒸汽在低压下冷却，冷凝液排出; 并且在需要很少或不需要密封水的真空泵中，所产生的富含SO 2的气体被压缩至大气压。

Abstract: In washing paper pulp or similar fibrous suspension the suspension is moved intermittently vertically through a column. In the dwell periods, washing liquid is forced through the fibrous suspension, and the resulting ''''extract'''' removed, in a generally horizontal direction through perforate screening members forming portions of the column.
